Composition-Safe re-parametrization in Distributed Component-based WSN Applications

Contemporary Wireless Sensor Networks like Smart Offices and Smart Cities are evolving to become multi-purpose application hosting platforms. These WSN platforms can simultaneously support multiple applications which may be managed by multiple actors. Reconfigurable component models have been shown to be viable solutions to reducing the complexity of managing and developing these applications while promoting software re-use. However, implicit parameter dependencies between components make reconfiguration complex and error-prone. Our approach achieves automatic composition-safe re-parametrization of distributed component compositions. To achieve this, we propose the use of language annotations that allow component developers to make these dependencies explicit and constraint-aware network protocols to ensure constraint propagation and enforcement.
